I keep my brace height at 1 1/8", I used to check it about every 30 seconds or so while shooting, the Boo string has eliminated the "what if" part of that, I no longer check it as often.
Sounds like my experience! I've found all my Excaliburs I've owned did best right at 1 1/8" brace height.
As for Boo's string I put my first one onearly inhunting seasonand checked it daily (target shooting and hunting, so it got a few shots every day) for two or three weeks before I finally got to give it a couple twists to shorten it. Haven't had to adjust it since. (a couple months now!)
